Manipur, a fertile and luxuriant geographical space of hills and valleys has been a host to migrants from many directions since the pre and proto-historical times. This geographical space is, today, the native home of people of Manipur who are categorised under; (1) official categories, such as, General, Other Backward Classes, Scheduled Tribes, and Scheduled Castes, and (2) broader social nomenclatures, such as, Kuki-Chin, Meetei/ Meitei (Bamons and Pangals inclusive), and Naga. The book studies the origin and relationship among these communities.
